Modifications may be resortedto within the spirit and scope of my invention.

That- I claim is: v

1. The combination of a container for molten glass having a plurality of outlet openings through which the glass issues, de-

vices for individually controlling the glass issuing from the respective outlets, and means to independently adjust said devices,

The combination of a container for molten glass having a plurality of outlet openings through which the glass issues, devices for individually controlling the glass issuing from the respective outlets, and means to relatively adjust said devices and thereby effect a corresponding relative adjustment in the amount of glass issuing from the respective outlets.

3. The combination of a container for molten glass having a plurality of discharge outlets through which the glass is extruded, means for periodically severing the extruded glass and thereby producing individual masses or gobs of glass, controlling devices individual to said outlets and controlling the size of said gobs, and means to relatively adjust said devices in a manner to vary the relative sizes of the gobs.

a. The combination of a container for molten glass having a plurality of discharge outlets through which the glass is extruded, means for periodically severing the extruded glass and thereby producing individual masses or gobs of glass, valves controlling said outlets, and means to independently adjust said valves and thereby independently adjust the size of gobs delivered from the respective outlets.

5. The combination of a container for molten glass having openings in the bottom thereof through which the glass issues, plugs extending into the glass above said openings, means to simultaneously reciprocate said plugs, and means to effect a relative vertical adjustment of said plugs.

6. The combination lOIE a container for molten glass having openings in the bottom thereof through which the glass issues, plugs extending into the glass over said openings, a head carrying said plugs, means to move the head up and down, and means to separately adjust the plugs up and down in said head.

7. The combination of a container for molten glass having outlet openings in the bottom thereof through which the glass issues, a mold having a plurality of mold cavities and movable into position to bring said cavitiesrespectively beneath said outlets, devices to control the flow of glass and thereby produce individual masses or gobs suspended from the walls of said outlets, means to simultaneously sever said gobs and cause them to drop into the mold cavities, and means to separately adjust said controlling devices and thereby vary the weight of the gobs.

8, The combination of a container for molten glass, having a plurality of outlet openings through which the glass issues simultaneously to form, a plurality of charges, regulating means by which the issuance-ofglass through each outlet opening is independently controlled, whereby the relative sizes of tlie'cl'iarges of glass issuing from the respective outlets may vary, and

means below the outlets to-sever the plurality of charges of glass.

9. The combination ota container for molten glass; having a plurality of downwardly directed outlet openings through which the glass issues, means for regulating the discharge of glass and causing it to be suspended from the walls of the outlet, said regulating means operable to cause a larger mass to be suspended from the walls of one outlet than from the other, and movable means to simultaneously sever said masses.

10. The combination of a container for molten glass having a plurality of outlet openings of equal size through which the glass issues, regulating means by which a larger quantity of glass is caused to issue from one outlet than from another, and

means to periodically sever unequal quantities of issued glass.

11. The combination of a container for molten glass having outlet openings in the bottom thereof through which the glass issues, periodically actuated means for controlling the discharge of glass and producing separate masses of'glass suspended from the Wallsof the respective outlets, said regulating means operable to cause a larger mass to be suspended tromone outlet than from the other, and means for severing the suspended masses.

12. The combination of a glass furnace having an extension communicating therewith, said extension having a plurality of outlet openings through which the glass issues, devices for individually controlling the glass issuing from the respective outlets, and means to independently adjust said devices.

13.- The combination of a glass furnace having an extension communicating therewith, said extension having a plurality of outlet openings through which the glass issues simultaneously toform aplurality of charges, regulating means by which the issuance of glass through each outlet opening is independently controlled, whereby the relative sizes of the charges of glass issuing from the respective outlets may vary, and means below the outlets to sever the pluralityof charges ofglass- 14. The combination of a glass furnace having an extension communicating theree wlth, said extension havlng a 'plurahty of outlet openings of equal size through which the glass issues, regulating means by which her, 1921.

a larger quantityo fdglass is caused to issue from one outlet than from another, and
